Edit table in pyqt using QAbstractTableModel

Question

I'm trying to create an editable table in PyQt. Here's the code for just displaying the table:

import sys
from PyQt4 import QtGui, QtCore
from PyQt4.QtCore import *
from PyQt4.QtGui import *

# données à représenter
my_array = [['00','01','02'],
            ['10','11','12'],
            ['20','21','22']]

def main():
    app = QApplication(sys.argv)
    w = MyWindow()
    w.show()
    sys.exit(app.exec_())

# création de la vue et du conteneur
class MyWindow(QWidget):
    def __init__(self, *args):
        QWidget.__init__(self, *args)

        tablemodel = MyTableModel(my_array, self)
        tableview = QTableView()
        tableview.setModel(tablemodel)

        layout = QVBoxLayout(self)
        layout.addWidget(tableview)
        self.setLayout(layout)

# création du modèle
class MyTableModel(QAbstractTableModel):
    def __init__(self, datain, parent = None, *args):
        QAbstractTableModel.__init__(self, parent, *args)
        self.arraydata = datain

    def rowCount(self, parent):
        return len(self.arraydata)

    def columnCount(self, parent):
        return len(self.arraydata[0])

    def data(self, index, role):
        if not index.isValid():
            return None
        elif role != Qt.DisplayRole:
            return None
        return (self.arraydata[index.row()][index.column()])

    """
    def setData(self, index, value):
        self.arraydata[index.row()][index.column()] = value
        return True
    def flags(self, index):
        return Qt.ItemIsEditable
    """    

if __name__ == "__main__":
    main()

If I implement the method setData and flags, all the items are not even selectable... What is the solution to make tha table editable? Thanks

I've just found the solution, in the flags methods need to return the value QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable

This works. You can also OR the already existing flags with the ItemIsEditable flag: QtCore.QAbstractTableModel.flags(self, index) | QtCore.Qt.ItemIsEditable

I tried your code. To work, I needed to change def setData(self, index, value) to def setData(self, index, value, role)

OR Override
Qt::ItemFlags MyTableView::flags(const QModelIndex& index) const
{
    Qt::ItemFlags flags = QAbstractTableModel::flags(index);
    flags |= Qt::ItemIsEditable;
    return flags;
}

@bigOTHER Not to mention, this code is in C++ while the question is regarding Python.
